Motorola and Microsoft have launched a clamshell mobile phone, based on Microsoft's Windows Mobile 2003 Smartphone software.
Mobile network operator Orange will distribute the phone for use on its UK network from October, and AT&T will offer it in the US in the fourth quarter.
The Motorola MPx200 is the third Orange phone to use Microsoft's phone software.
Orange launched the SPV, the first Windows Powered Smartphone available worldwide, last October, and brought out an upgraded version earlier this year.
Orange has worked with Motorola to customise the phone to its own needs,said Stuart Jackson, Orange's corporate communications manager.
Like the SPV, it comes branded with the Orange logo, has an Orange user interface and offers services such as Orange Backup, where users can store their data on the Orange network in case of problems with their phone.
The MPx200 allows users to surf the internet, access their e-mails and synchronise the phone with their PC. It includes an SD slot with a 16Mbyte memory card (a 2Gbyte card is available), an external speaker for listening to MP3 and Windows Media files and can play videos using Windows Media Player. A detachable camera is available separately.
In the UK the MPx200 will cost £239.99 with an Orange contract.
The phone will also be sold in Hong Kong from the fourth quarter, and negotiations are under way with operators in other European and Asian markets.
Motorola and Microsoft plan to develop jointly a series of Smartphone and Pocket PC products, including a PDA. These will be made available internationally once partner operators are found.
Orange has sold 100,000 SPV Smartphones in Europe, Jackson said, adding that the revenue from data services has been high.
"The average user is accessing the internet five times a day; 60% use it to get their e-mail, and 85% have synched it with their PC. So people are really using them," he said.
